Title: Improvements in and relating to semiconductor devices
IPC: H01L21/22
Filed: 1966-12-05
Abstract: 1,142,068. Semi-conductor device. INTERNATIONAL BUSINESS MACHINES CORP. 5 Dec., 1966 [14 Jan., 1966], No. 54311/66. Heading H1K. A method of manufacturing a semi-conductor device comprises the steps of forming openings in a masking layer on a surface of a semiconductive wafer of a first conductivity-type, diffusing an impurity through said openings to produce spaced regions of opposite conductivity-type at the surface of said wafer, said spaced regions being of the same conductivity type and having a gap therebetween, forming another opening in the masking layer on said surface overlying said spaced regions, diffusing an impurity therethrough to produce another region of said opposite conductivity type which with said spaced regions forms a base region for said device, and thereafter diffusing an impurity into said base region to produce an emitter region overlying a portion of the base region defined by said gap. Boron is diffused at 970 C. into an n-type Si wafer 10 through two openings in a silicon oxide mask (12), to give two separate p-type regions (16, Fig. 2a, not shown). In a second diffusion step an additional area is opened in the oxide mask overlying the two regions and more boron diffused in to give a shallow p-type region (22) connecting the two regions together (Fig. 3a, not shown). An oxide layer 24 having an opening 26 is then provided and phosphorus diffused in at 900 C. to give an n-type emitter region 28. An ohmic contact 40 is provided for base region 30. In an alternative embodiment, the mask opening for the second diffusion stage may have the same width as that used in the third stage.

Title: Insulated gate field effect transistors
Inventor: BEER ANDREW FRANCIS
IPC: H01L29/78
Filed: 1965-12-22
Abstract: 1,136,569. IGFETs. MULLARD Ltd. 22 Dec., 1965, No. 54333/65. Heading H1K. The invention relates to double gate versions of the insulated gate field effect transistor which operate in the enhancement mode and to this end have overlapping gate electrodes to ensure continuity of the conduction path. A signal and bias are applied to the gate furthest from the drain; this arrangement ensures that the capacitive feed-back from drain to signal gate is less than in single gate devices. Other semiconductor devices may be formed in the same body to produce integrated circuits. Figs. 3 (not shown) and 5 depict IGFETs each based on a P-type silicon body having N<SP>+</SP> source and drain regions and grown silicon dioxide gate insulation. The deposited aluminium gate electrodes of Fig. 3 overlap only at their edges where they are mutually insulated by silicon oxide pyrolytically deposited from tetraethoxysilane. The signal gate 33 of the Fig. 5 device lies on grown silica with the second gate electrode 38 completely overlying it as shown and insulated from it by pyrolytically deposited oxide. Bias on the second gate produces the extremities of the conduction path while the potential on the signal gate produces the centre portion. The transistors may be mounted on headers and conventionally encapsulated.

The mechanism 1 comprises a disc (10), Fig. 1 (not shown), normally held against the action of a compressed spring (4) by a latch 9, but automatically released by retraction of latch on failure of the power supply, whereby the disc is moved by the spring to move rod 5 and rotate planet carrier 14 in a direction resulting in valve closure until abutment 27 contacts switch and stop 24. On resumption of the power, supply lead 36 conveys a signal which causes control means 28 to rotate the motor 19 in the valve closure direction causing the disc (10) to return to its locked position behind latch 9 and to actuate a switch 38 to de-energize the motor. Thereafter energization of the motor for opening and closing the valve is controlled by knobs 29, 30. The safety mechanism may comprise two spring-biased discs (10) and rods 5, the latter being symmetrically connected to the planet carrier 14.

Title: Movement Direction Determining Apparatus
IPC: G06V30/144
Filed: 1966-12-21
Abstract: 1,165,720. Pattern recognition. INTERNATIONAL BUSINESS MACHINES CORP. 21 Dec., 1966 [5 Jan., 1966], No. 57198/66. Heading G4R. Apparatus for determining the direction of movement of a body comprises movement circuitry producing signals for moving the body in a first circular path, control circuitry for producing signals for moving the body in a second circular path of different radius under the control of a variable control factor, and indicating circuitry coupled to the movement circuitry producing continuously a signal representative of the direction of movement of the body when moving in the second circular path. In a first embodiment, a flying-spot scanner follows the outline of a character by being fed with sin and cos deflection voltages derived from an oscillator to produce a circle scan whose radius is reduced when the spot is on the character as distinct from the background. The sin and cos voltages and a minus cos voltage also derived from the oscillator are compared with each other and earth to produce signals specifying in which if any of four overlapping 180 degree sectors the direction of movement of the spot lies. Whenever the spot is on the character itself, these signals are enabled to set triggers the outputs of which are decoded in AND gates to specify one of eight compass directions. In a second embodiment, the radius of the scan is increased from 255 degrees after the spot moves on to the character until 30 degrees later. Sin and cos deflection voltages are derived by filters and integrators from selectively-attenuated square waves produced by two triggers controlled by a 12-stage ring counter. Whenever the radius of the scan is increased by deactivating the attenuators, the state of the counter is stored to indicate the direction of movement of the spot. The direction of movement of the spot, thus repetitively determined, specifies the shape of the character for character recognition purposes and enables trapping of the spot within a hollow space in the character to be detected.

Abstract: 1362599 Comminuting foundry sand; screening and air sifting apparatus CARBORUNDUM CO 22 Dec 1972 [3 Jan 1972] 59496/72 Headings B2A and B2H Apparatus for comminuting moulded sand comprises a first surface 19, which may have serrations 29 and a discharge end 21 for sand lumps, a second surface 25 below the first surface 19, which may included a plurality of apertures 23, means to project abrasive particles in a path toward the second surface, e.g. a throwing wheel 35 and means to oscillate the two surfaces. The surfaces are supported by a trough 11 and are oscillated either by a pneumatic or hydraulic piston and cylinder 37 or electrically or mechanically, e.g. on a release or push-pull cycle. A shoulder member 49 beneath the surface 19 causes lumps to be pushed forward under the path of the abrasive particles due to the forward motion of the trough, across a plate 51. The lower surface may include serrations rather than a screen, and the wheel 35 may be inclined towards the shoulder 49, so that the stream strikes the plate 51 adjacent the shoulder. The sand-shot mixture discharged from the bottom of the trough 11 is subjected to an air curtain. Skimmer plates in a separating chamber sort the mixture into two streams according to weight. The abrasive (heavy) particles fall into a discharge conduit and the (light) sand is deflected into another conduit. The surface 19 comprises serrations 29 in the form of slats extending across the trough 11. The serrations can be separated by a small amount to permit loose sand to fall to the bottom of the trough.
